Abstract: A communication switching method is provided. The method is implemented by a communication switching system. The system includes mobile phones, landline phones, and a RFID server. Each mobile phone includes a RFID tag. Each landline phone includes a RFID reader. The RFID server includes a database. The method includes: putting the call on hold through the IP-PBX; transmitting the mobile phone number of a called mobile phone to the RFID server; searching the database to determine whether the mobile phone number is registered; transmitting the landline phone number corresponding to the mobile phone number to the RFID reader when the mobile phone number is registered; determining whether the landline phone corresponding to the landline phone number is busy; and switching the call to the landline phone corresponding to the landline phone number through the IP-PBX when the landline phone corresponding to the landline phone number is idle.

Abstract: A fluid applying pen, the pen mainly has therein a hollow main pipe for receiving fluid material, the upper end of the main pipe is connected and communicated with a silicone head with a bevel surface having spines, while the lower end of the main pipe is connected with a pusher mechanism; the pusher mechanism has a rotation knob provided over the lower end of the hollow main pipe; when the rotation knob is rotated relatively to the main pipe, a pusher rod of the pusher mechanism extending into the main pipe may move a pusher annulus linearly along the wall of the main pipe, so that the fluid will flow out of an opening provided on the silicone head. The bevel surface having spines of the silicone head is convenient for contact with a skin, so that the fluid can be uniformly applied on the skin of a user, and meantime an effect of massaging can be obtained.
